Impressive. Now, let's get back to our work, as "what matters in the end is what people choose to do." And we'll for sure still learn a lot making Pharo a great platform (we do not have Wolfram's 700 individuals engineering force). I'd vote for a Pharo integration like they show for Python and Java. Who knows someone over there?

Looking forward to it. Yes, I think you and your team have done a lot to move in the right direction, thanks a lot. If you want to reach a larger audience, try to go as light as possible on the actual Smalltalk code, even if you have to cheat a bit by choosing good looking examples - the effect is more important than the actual syntax, but complex foreign code scares away everyone.

Sorry for no replying. That actually seems to be a shader bug in Roassal3D.

Re: [Pharo-dev] [Inspiration] Toward a better programming

I cannot resist to jump on this. Indeed, we have the moral obligation to promote what we have crafted over the year. Producing a high-quality video has been on my todo list for quite some times already. As you probably know, we did some intent already (videos about Roassal, GraphET, and other tools), but we were too young maybe. Within the next few weeks we will work on a cool video to promote Roassal2, and our goal is to reach users beyond the Smalltalk boundary. We have everything so far. The moose distribution is a wonderful toolbox that can literally blow away any example shown in this video. As you may have seen, we have worked on Roassal2 which includes a new geographical map builder, tabular table importer, GraphET2, fancy curves, html and amber exporter. A video carefully orchestrated has the potential to kick away Aurora, Light Table, Wolfram and all their friends. We will soon get there...

Will Nautilus scrolling bug be fixed for Pharo 3.0 release?

by Marco A.

Occasionally, when I use my trackpad to scroll through my classes (the 2nd column in the Nautilus window), the package pane starts scrolling (1st column) even though the cursor has never moved outside of the left-and-right bounds of the 2nd column. I looked in read-only Pharo-issue tracker via Penelope http://bugs.pharo.org/ in the Cases for UI to see if someone had already reported this but found that the last post there was March 2013. Although I'm trying to learn enough to be able to contribute, I think fixing this is out of my reach for now. I inspected the Nautilus class but got stuck trying to see how mouseMoved events were sent and handled to the Nautilus window. Do you think this will be fixed for the Pharo 3.0 release? - Marco A.
